Application of quantum theory of electrons to the mechanical and thermal properties of metals
(The University of Edinburgh, 1940-11)
The first successful application of quantum mechanics to the problem of metallic cohesion was made by Wigner and Seitz (1938) They appoximated sodium metal by a number of isolated spheres of equal atomic volume and integrated, ...
On the divergence difficulty of quantized field theories and the rigorous treatment of radiation reaction : with related additional papers
(The University of Edinburgh, 1945-04)
By an orthodox application of the perturbation theory to the general case of a quantized field, it is shown that the divergence difficulty hitherto encountered arises from a faulty application of the expansion method. The ...
